Purpose Pulmonary vein (PV) isolation (PVI) by point-by-point radiofrequency application
(PPRF) results in longer procedures than that achieved by single-shot ablation techniques …

Introduction High-power short-duration (HPSD) radiofrequency ablation has been proposed
to produce rapid and effective lesions for pulmonary vein isolation (PVI). We aimed to …

Introduction Negative component abolition of the unipolar signal (unipolar signal
modification [USM]) reflects the lesion transmurality. The purpose of this study was to …

Background: Although proposed to facilitate pulmonary vein isolation (PVI), high-power
ablation may favor extracardiac damage. Negative component abolition of the unipolar …

Background High-power, short duration (HPSD) radiofrequency ablation (RFA) is a
commonly used strategy for pulmonary vein isolation (PVI). Objectives This study sought to …

Aims Pulmonary vein isolation (PVI) using radiofrequency ablation (RFA) in patients with
paroxysmal atrial fibrillation (PAF) is effective but hampered by pulmonary vein reconnection …

Aims Very high-power short-duration (vHPSD) via temperature-controlled ablation (TCA) is a
new modality to perform radiofrequency pulmonary vein isolation (PVI), conceivably at the …

Background: CLOSE-guided atrial fibrillation (AF) ablation is based on contiguous (intertag
distance≤ 6 mm), optimized (Ablation Index> 550 anteriorly and> 400 posteriorly) point-by …

Aims The very high-power short-duration (vHP-SD) radiofrequency (RF) ablation concept of
atrial fibrillation (AF) treatment by pulmonary vein isolation (PVI) aims for safer, more …

Background Very high-power, short-duration (90-W/4-second) ablation for pulmonary vein
isolation (PVI) may reduce procedural times. However, shorter applications with higher …
